Skyrim: New Allegiances
New Allegiances is a side (Radiant) quest in Skyrim: Dawnguard.
New Allegiances is only available to Vampire Lords.
 Starting Location
The quest New Allegiances starts in Castle Volkihar
 Quest Giver
New Allegiances is given by Vingalmo.
Vingalmo has sent me to (random town) where I am to find Valindor and bestow the Gift of Blood upon him. I should first render him pliant through the use of Vampire's Seduction then embrace and bite him on the neck. If I currently lack the power, I should forego feeding for a day as I will gain the ability. I should then return to Vingalmo while (random NPC) undergoes the change.
Turn (random NPC) into a vampire
Travel to the town you were told to go, and find the target. Use your Vampire's Seduction power on it (If you don't have that power, wait outside for a day until you get it). Then interact with the character (pickpocket button) and choose to feed on him.
Return to Vingalmo in Castle Volkihar when you are done.
 Potential Victims
Potion of Blood (3)
 Post Quest Abilities
If you later return to the NPC, there is extra dialog options, and a coffin in his house which you can use.
